AUTOMATlC CO|N-OPERATIED DEVICE.

SPECIFICATION forming part of Letters Patent No. 399,643, dated B'Iarch12, 1889.

Application filed November 24, 1888. Serial No. 291,760. (No model.)

To whom it may concern:

Be it known that I, BARTON S. MOLYNEUX, of Minneapolis, in the countyof, Hennepin and State of Minnesota, have invented new and usefulImprovements in Automatic Coin- Operated Devices, of which the followingis a Specification.

My invention relates to improvements in selling, exhibiting, and othersimilar devices operated by means of a coin, representing the price orfee which is deposited therein; and it consists, generally, in thearrangement hereinafter described, and particularly pointed out in theclaims.

In the drawings my device is shown attached to a IIQUICI'IGSGI'VOI1',and by its valvular connection constitutes an automatic liquid measurerand releaser, but is suitable for any other purpose where the mechanismis to be operated in a similar manner.

In the drawings forming a part of this specification, Figure 1 is avertical longitudinal section of my device. Fig. 2 is a verticalcross-section 011 the line w m of Fig. 1. Fig is a vertical longitudinalsection showing the position of parts when operated.

In the drawings, 1 represents a box or case inclosing the device,preferably constructed of cast metal and having its lower portiondetachable for the purpose of giving access to the mechanism andremoving the coins deposited therein.

3 is a plunger having the spring 5, and sliding freely in the guide ortube 7, which incloses the spring 5.

9 is a rod or shaft, which in the drawings is shown as a valvestem, towhich motion is imparted by means of the plunger in the mannerhereinafter described. This rod is fitted preferably with a cup-shapedhead or seat, 11, into which the extremity of the plunger is projectedwhen pushed inward, as shown by dotted lines in Fig. 1, when there is nocoin in position in the device tomake it operative. Instead of thecup-shaped head the rod 9 may be fitted with suitable prongs or otherequivalent attachment, which will serve as a seat or support for thecoin 13, and will admit of the same motion of the plunger 3 in theabsence of the coin without being itself moved.

15 is a yoke, one arm of which is rigidly secured to the rod 9, theother being fitted with asuitable-orifice, through which the plunger 3freely moves. A stop, 17, is secured to the plunger 3 on the inner sideof the yoke, by means of which the plunger, when released and thrownoutward by the spring 5, engages the yoke and returns it from theposition shown in Fig. 3 to that shown in Fig. 1.

i9 is a conduit secured in the case 1, so as to connect with the opening23 in the top of the case, and is adapted to conduct a com dropped.through the opening to a second conduit, 21, which in turn conducts itto a position between the plunger and the seat 1.1, where it rests againthe stop 25, which holds it in position to receive the plunger 3.

I prefer to use the conduits arranged as described, in order to preventtampering with the machine, as could readily be done if the conduit werestre ight from the opening 23 to the exit end of the conduit 21.

27 is a cask or reservoir to which this device is shown applied as afluid-releaser.

29 is the receiving or measuring tank located in said reservoir andhaving pipe-connection with the interior of the reservoir and an outlet,31.

f is a valve attached to the rod 9, and

03 adapted, when operated by the device as above described, to close theconnection between the tank 29 and the reservoir 27, and to opencommunication between the tank 29 and the outlet-pipe 31.

The mode of operation of my device is follows, in the connection andadaptation shown in the drawings. The object is to draw into a cup orother receptacle, placed under the outlet-pipe 31, the contents of thetank 29. A suitable coin is dropped into the opening 23, and is carriedby the conduits 19 and 21 downward until it strikes the stop 25, bywhich it is held directly in front of the plunger 3 and between it andthe head or seat 11 in the position shown in Fig. 2. The plunger is thenpushed inward, strikes the coinand presses it against the seat 11, themotion bein g transmitted thereto, the valve 33 is opened, communicationis established between a tank .the yoke and draws it outward.

to flow out. The tank 29 having been emptied, or the desired amount offluid having been drawn therefrom, the plunger is released, the spring 5serving by its tension to throw it outward. The coin 13 being releasedfrom pressure between the plunger and the seat 11, falls into the bottomof the case 1, the stop 17 engage the yoke 15, drawing it outward, thusclosing the valve. Communication being thus re-established between thetank 29 and the reservoir27, the tank is again filled from the contentsof the reservoir, and another coin may be deposited in thedevice, andthe same operation repeated. The stop 17 is secured to the plunger 3, soas to allow a slight play between it and the arm of the yoke, as shownin Fig. 3. This insures the releasing of the coin when the plunger isrelieved of pressure, since the plunger will move away from the coin thedistance between the stop and the yoke before the stop engages It istherefore impossible for the coin to remain in the device so as tooperate the valve more than once.

As shown in Fig. 1, it is absolutely impossible to operate the devicewithout the interposition of the coin, since the plunger, when pressedinward, will enter the cavity in the seat 11, and the valve will not bemoved.

I claim as my invention 1. In a device of the class described, the

combination, with the plunger 3, having the spring 5 and the stop 17, ofthe rod 9, having the yoke 15, and the seat 11, adapted to receive andsupport a suitable coin interposed between it and the plunger, by meansof which motion is transmitted from said plunger to said rod 9,substantially as described.

2. In a device of the class described, the combination, with a suitablesupport or case, 1, having a suitable coin-conduit fitted with asuitable stop, 25, of the plunger 3, the yoke 15, and the seat 11,adapted to receive and support a suitable coin interposed between it andthe plunger, substantially as described.

3. The combination, with the reservoir and the receiving-chambcr, of thevalve arranged to control the ilow of liquid from saidreceiving-chamber, the valve-rod provided with a seat having a cavitytherein, a plunger provided with a stem adapted to enter the cavity insaid seat, a coin-conduit arranged to conduct a coin to a positionbetween said plunger and said seat, and a stop arranged to arrest saidcoin in such position, substantially as described.

In testimony whereof I have hereunto set my hand this 15th day ofNovember, 1888.

BARTON S. MOLYNEUX.
